In honor of Earth Day, you may consider planting a Moon Garden. Given the choice, I'd probably turn the entire backyard into a garden (but somehow I don't see my parents going for that).
A Moon Garden is one filled with those plants that have white or light yellow/pink flowers, many of which are nocturnal in nature. The best known of these is, somewhat obviously, the Moonflower. The Moonflower is a climbing plant, cousin to the Morning Glory, whose flowers only open at night. The white flowers smell slightly of lemon, and, when open, are about 5 - 6 inches in diameter. Phlox, one of my favorite flowers, has a nocturnal variety, called the Night Phlox. These smell like honey, and open at twilight. A final intriguing such plant is the Angel's Trumpet, which opens in the evening in a horn shape, with a strong, floral scent. One could also consider mixing in non-flowering plants with silver leaves, such as Lamb's Ear, or diurnal white flowers to continue the look in the daytime.
To make your garden, check the planting instructions of all species you intend to plant. Make sure that the garden size you plan on can accommodate your new friends. Then, if not already available, dig the area for your plants, or, if space is limited, purchase pots. Consider making your garden circular or in the shape of a half or crescent moon. Plant your plants, add any stepping stones or statues (preferably keeping to the white and silver theme) as desired, and then hold a small ritual outdoors to dedicate the space to the Goddess.
